The Innersound amps are pretty nice for the $$... you might
research their heritage though...
There are several ESLs with a benign load impedance curve. The Acoustat stands out as one without any dips below 6 ohms. It all depends upon the drive circuit. I think the Audiostatic has a patented circuit that has similar benefits.
The issue is where do you match the "cells" along their 6dB/oct slope from low freq/high impedance to high freq/low
impedance.
The idea is to NOT match them at one point but at at least two, keeping the impedances in hand... that's what the better full range panels do. The multiway ones (Quad 57) do that automatically...
